Abstract
A touch sensing method is described as well as related methods and systems. In some embodiments of the touch sensing method, energy of a drive signal is allocated among frequencies of RF subcarriers such that the allocated energy meets electromagnetic emissions requirements for the application of a touch sensing system implementing the touch sensing method. Also described are methods of determining a spectrally shaped time domain digital waveform for use in generating a spectrally shaped drive signal.
